Gas heat, where Énergir's line actually runs.

Partially. Énergir serves real portions of Longueuil and the rest of the south shore, particularly older, denser sections and commercial corridors, but coverage isn't universal—some newer subdivisions and outlying streets have no gas main nearby. Before you shop for a fireplace, it's worth confirming your address against Énergir's service territory; a local dealer who works in Longueuil regularly can usually tell you within a phone call whether your street is served or whether propane is the more realistic path.

Typical installs run $6,000 to $15,000 CAD. A direct-vent insert dropping into an existing masonry firebox on a home already tied into Énergir's line sits toward the lower end. A new built-in unit for a renovation or addition—especially one needing a fresh gas line run or venting through an exterior wall—lands toward the top. Homes that aren't on the Énergir network and need a propane tank set instead of a buried gas line should budget a bit more on top of the base install.

Yes, through propane. It's the standard workaround across Montérégie for homes outside Énergir's footprint, using a tank instead of a utility connection. Most gas fireplace models a trusted local dealer carries can be configured for either fuel, so the appliance choice usually isn't the constraint—the tank or line setup is what changes your cost and timeline.

Hydro-Québec's residential rate, around $0.078 per kWh, is low enough that baseboard and central electric heat remain the default across most of the province, and Longueuil is part of that pattern. Wood also has deep roots here—sugar maple, yellow birch, American beech, and red oak are all cut locally under Ministère des Ressources naturelles et des Forêts permits—and it stays popular as backup heat during Quebec's occasional winter outages. Gas fills a narrower role: it's a comfort and convenience upgrade for homes that happen to sit on Énergir's line, not the default heating fuel.

Yes. You'll need a permit through Longueuil's municipal building department, and the installation itself has to meet the CSA B365 code that governs solid-fuel and gas-fired appliance installations in Canada, plus licensed gas-fitter work for the line itself. A dealer who handles gas fireplace projects regularly in Longueuil will typically manage the permit application and coordinate the gas-fitter as part of the project rather than leaving you to juggle two trades separately.

Direct-vent units draw combustion air from outside and exhaust it back outside through sealed venting, and they're the standard, code-compliant choice for daily use in cold-climate Quebec homes that are often tightly sealed for winter efficiency. Vent-free units burn into the room and carry strict square-footage limits under the applicable codes. Given how airtight modern Longueuil construction tends to be to cope with the cold, most local dealers steer homeowners toward direct-vent so indoor air quality and moisture aren't a concern over a long heating season.

A gas fireplace is a built-in unit framed into a wall, common in newer construction or a full renovation. A gas insert fits into an existing masonry firebox, which is the more common upgrade in Longueuil's older Vieux-Longueuil homes that already have a chimney chase in place. A gas stove is freestanding on a hearth pad, similar in footprint to a wood stove but tied to a gas line or propane tank instead of cordwood. For a home already on Énergir's network with a working chimney, an insert is usually the least disruptive route.

Plan on an annual check, ideally in late summer or early fall before Longueuil's first real cold snap rather than mid-winter when technicians are booked solid. A technician checks the burner, pilot assembly, gas connections, and venting, and cleans the glass. It's a lighter job than a wood chimney sweep, but skipping it on a unit that runs daily through a cold five-month season is how an ignition problem shows up on the coldest night in January.

If Hydro-Québec's $0.078/kWh rate already heats your home affordably, choosing gas mainly comes down to ambiance and convenience—gas needs a battery-backed ignition system to keep working without power, while a wood stove burning local sugar maple or oak works with no electricity at all. On the island of Montreal, wood stoves also need to be registered and certified low-emission under the municipal bylaw limiting fine-particle output; Longueuil residents installing wood heat should check their own municipal rules, which a local dealer handling installs in the region will know. For most Longueuil homeowners already on Énergir's line, gas ends up being chosen for convenience and instant heat rather than as a primary heating replacement.

Most modern gas fireplaces can—turn it on and off from the couch with a remote, or set a room temperature and let the fireplace hold the comfort zone for you. If low maintenance matters to your family, this is the feature set that makes gas the convenience pick over wood and pellet.

Because a fireplace is an iceberg—there's more behind the wall than in front of it. A low quote often covers only the unit; the full scope includes vent pipe, gas line or electrical, framing, and the tile or stone that has to come off and go back on. Make every bidder price the whole job. If a dealer can't speak to the full scope with confidence, that's your signal to keep looking.

Fireplaces are like icebergs—bigger behind the wall than in front of it. Replacement means removing the surrounding tile or stone (the finish material laps onto the fireplace face), pulling the old unit, setting the new one in the same enclosure, and re-finishing the wall. A hearth professional can determine what's behind your wall without demolition during an in-home preview.

Open fireplaces suck—literally. As the fire burns, it consumes air your furnace already paid to heat and pulls it out through the chimney, so the house is actually colder after the fire goes out than before you lit it. An insert fixes this: it seals the chimney, puts fixed glass across the front, and turns that hole in your house into a real heat source.
